How the Presbia Corneal Inlay from Optilase Works

06 Oct 2013

To understand how the Presbia intrastromal inlay works to correct presbyopia, it can be likened to a contact lens, only that it is implanted into the cornea rather than slotted in front of it.

 

The Presbia microlens is a clear disc that changes the refractive index of your cornea, so that you can clearly see objects up close. It is only suited to treat presbyopia and cannot be used to counteract any other refractive errors.

Cutting edge design

Designed to be only 3mm in diameter and only 15 microns in edge thickness (1/4 width of a single human hair), the Presbia microlens is designed to incorporate different refractive power.

 

If you think of the microlens like a ring doughnut, there is a 1.8mm central zone that does not have any refractive power, which allows for distance vision to remain largely unaffected.

 

It is the outer ring that is the refractive powerhouse, suitable for prescriptions +1.25D to 3.50D that has revolutionized near vision correction for presbyopic patients.

Biocompatible with corneal tissue

Using the latest advances in biotechnology, the Presbia microlens is compatible with the biological processes that take place in the cornea and will not aggravate surrounding tissue.

 

A 0.15mm hole at the center of the lens allows for fluid, oxygen and nutrients to flow through to maintain optimal eye health.

How the inlay works to correct vision

Far vision: Light rays pass through the central zone and the surrounding corneal tissue not covered by the lens and refracts as normal to focus on the retina. Any light that passes through the refractive peripheral area of the Presbia inlay are focused in front of the retina.

 

Near vision: Light rays that pass through the refractive zone of the Presbia inlay are focused on the retina, while those that enter the central zone will focus behind the retina. Remaining light that go through the rest of the cornea will be blocked from reaching the back of the eye by the pupil.

 

The entire procedure takes only ten minutes and sight normalizes within a few days so you can put down the reading glasses and enjoy a whole world of vision!

Couldn't rate Optilase high enough. I had Lens Replacement Surgery. My experience from the first phone call to the procedure itself and the aftercare was fantastic. All of the staff from the call centre to the staff in Carrickmines and the theatre were so helpful and friendly. Would definitely recommend .

Got LASIK in Ely Place only yesterday and officially had 20/20 vision just 24 hours later! Cannot recommend Optilase enough from my initial consultation with Aisling in Athlone to my trips to Carrickmines and Ely Place. The staff really look after you from the moment you walk in the door and make you feel so at ease from start to finish - 10 out of 10 experience!

I have been wearing glasses for over 20 years. I always hated wearing contact lenses and I got to a time in my life that I needed a change. A friend recommended optilase, I went for the free consultation and the person that did all the exams was really nice and I felt safe and confident enough to go ahead, I was recommended the PRK. I Put on a piece of paper how much I spent and would still spend on glasses for the next 10 years, and the surgery was for sure cheaper than that. My prescription was very high, both eyes, myopia and astigmatism Optilase provided all the information I needed, in clear manner. And they always made clear that there was nothing wrong with my eyes, it was my own choice to go for the surgery. The day of the surgery I was a bit nervous, who wouldn't? But then, from the reception to the surgeon, they were all so nice and welcoming. Hernandez performed the procedure, lovely surgeon, again all information was provided the way it should. I was instructed in what I should and should not do. The actual procedure took less than 15min, I felt nothing, no discomfort or anything. The whole process is very well done by the team, if I remember well around 3 people supporting the surgery plus one other girl providing pos surgery instructions. Right after the procedure I could already see much better than before without glasses! I couldn't believe it, I cried, thanked everyone and left the clinic knowing that I made the best choice. The recovery for PRK is a bit longer, I stayed for 2 full days no phones, or any screens. In the dark. If you have a little one, I would recommend to have someone minding them, as you are very limited in what you can do for the day of and day after surgery. It is hard to open the eyes, the second day after surgery was the toughest, I thought all went wrong as the vision got worst, but again I was advised it could happen. Note that this was my experience and could be different for other people. The 3rd day I felt nothing and could see much better already. Light sensitivity was very high, and still, 6 days after surgery, but nothing that a sun glasses would not help. My vision still blurred, but I need no glasses to see, my eyes feel dry sometimes, but the eye drops provided helps with it and and am very happy with the results already, even knowing it takes a bit longer to fully recover the vision. I'm back to work (screen at 200% to make sure I dont force my eyes too much) and I have had no headaches or anything, which I would have all the time looking at screens for most of my day. I cannot recommend Optilase enough, they are amazing! If you want to do something for your self and want a place you can trust, go for it, choose Optilase. Thanks to the whole team for one of the best things I did for my self!

Surgeon was great! Talked me through everything as the surgery was happening. Bit of discomfort during surgery and very painful for 2-3 hrs after but put more drops in and took a nap and then completely fine after. Colette for my consultation and post op was so friendly and helpful. Overall, great experience.

I highly recommend Optilase for laser eye surgery. The process from the initial consultation to the post surgery check ups was quite smooth and professional. The staff working at the clinic was very knowledgeable, professional, and friendly. The surgery was over in minutes and I didn't feel any pain. The doctor kept an open communication with me during the surgery what made a big difference.
